NEW YORKyN. Y., A CORPORATION OF NEW YORK I WEB-CLEANING MECHANISM Application filed August 21, 1926. Serial No. 130,566.

This inventionrelates to certain improvements in removing lint or similar dirt from a web roll while the roll is unwinding.

In web presses where the web is supplied continuously from a web roll, lint or paper fibre or similar dirt is apt to be formed on the unwinding web, particularly where ,devices are employed contacting with the Web roll for controlling its unwinding, as now common in handling or controlling web rolls. This lint is carried by the web through the press and frequently collects or deposits in such a manner as to interfere both with the operation of the printing mechanism itself and with proper printing where it is deposited in sufficient quantity in stereotype plates, as is frequently the case,

It is the especial object of the present invention to provide a device which will act to remove the lint, dust or the like from the web as it unwinds, thereby preventing this deleterious matter from being carried into the press. i

lit is a further object of the invention to utilize the web controlling devices for effecting this where such web controlling devices are used for controlling the unwinding of the roll, the construction being a simple one which can be readily installed with mechanisms already in use as well as with new machines.

With these and other objects not specificaliy referred to in view, the invention consists in certain novel parts, arrangements and combinations which will be described in connection with the accompanying drawings and the novel features pointed out in the claims hereunto annexed.

lln these drawings,-

' Figure 1 represents a diagrammatic arrangement of a web roll support capacitated to carry a running roll and a spare roll, the web being led to a printing mechanism not illustrated Figure 2 is a side view of one form of lint removing device which may be employed, this form being a wide belt; I

Figures 3, l and 5 are detail views showing narrower belts and difierent ways in which further modified which is pivoted a frame 4 carrying a pair of arms 5, 6, on opposite sides of the pivot point, it being understood that this construction is duplicated on the other side of the support. These arms 5, 6, are provided with supported, 8, for the roll spindles 9, 10, which support the running roll R and a spare. roll S. Suitable guide rolls ll, 12, are provided for the web running from either roll, these guiderolls being mounted on arms It, 15, carried by the frame 4:, before referred to. The web is led through suitable draw-0E rolls 16, 17, to the press, not shown.

in accordance with. the invention, devices are provided for removing the lint or dust or like dirt from the web as it unwinds. While these devices may be of various characters, in the particular construction illustrated certain tension devices are provided for controlling the unwinding of the roll and, where such devices are employed, these may be so constructed and arranged as to effect the function of removing the lint from the roll as the roll unwinds.

In the particular construction illustrated, these tension devices are in the form of belts or straps 18, 19, one or more of these belts being provided for each of the rolls. These belts are secured over rods 20, 21, supported from the arms it, 15, before referred to, and are or may be free at their other ends, hanging over the rolls, as shown in Figure 1. These belts, it will be observed, engage a considerable part of the roll surface and, in addition re their function of controlling the roll as it unwinds, also act to brush or rub off the lint or other dirt from the surface of the unwinding web.

While the belts may be variously formed for doing this, as shown in Figure 2, there is provided a wide belt 22 which extends substantially the width of the paper roll. This wide belt is provided with narrow apertures or slits 23 arranged in line across the belt, the slits in one of the lines, as indicated by the letter a, being off-set with respect to those in in Figures 3, 4 and 5 may be provided. In

this construction, instead ofthe wide belt 22, there are provided a plurality of narrower belts 24, these belts being provided in sufficient numbers across the roll and the slots may be arranged in these belts in various ways. As shown (see Figure 3) the arrange ment is that shown in Figure 2, the slots extending widthwise of the web. In Figure 4 they are shown as extending longitudinally of the web and in Figure 5 diagonally of the web, while in Figure 6, instead of the slots, holes 25 may be formed in the web which answer the same purpose.

If desired, the edges of the belt may be reinforced as by the tape 26, shown in Figure 2, or stitching 27, indicated in Figure 3.

It will be observed that with the construc tion shown and described, any deleterious amount of lint or dirt is removed from the web and by utilizing the web controlling devices for doing this, any lint or dirt stirred up by them is likewise removed so that the web goes into the press under proper tension and sulficiently clean so as not to cause any trouble afterwards.

While the use of the roll controlling devices for effecting this function is a convenient one when these are used, it is to be understood that the invention is not to be so restricted, but that the removing devices may assume various forms and arrangements other than those shown and described without departing from the scope of the invention as defined in the appended claims.

What I claim is 2 1. The combination with a web roll and means for supporting it while unwinding, of tension producing means engaging the surface of the unwinding roll and provided with means formed to remove surface lint or the like therefrom as the roll unwinds.

2. The combination with a web roll and means for supporting it while unwinding, of flexible tension producing means engaging the surface of the roll for controlling the unwinding of the roll, and provided with means formed to remove surface lint or the like from the surface of the roll while the latter unwinds. c

3. The combination with a web roll and means for suporting it while unwinding, of a belt engaging the surface of the roll for controlling the unwinding of the roll, and provided with apertures through which lint or the like may be removed from the surface of the roll while the roll is unwinding.

l. The combination with a web roll and means for supporting it while unwinding, of a belt engaging the surface of the roll, and provided with slits arranged widthwise thereof and in staggered relation in respect to each other through which lint may be removed from the surface of the roll while unwinding.

5. The combination with a web roll and means for supporting it while unwinding, of a belt engaging the surface of the roll, and provided with apertures arranged in off-set relation to each other through which lint may be removed from the surface of the roll as the roll unwinds.

6. The combination with a web roll and means for supporting it while unwinding, of a flexible tension device engaging the roll surface and provided with apertures through which lint or the like may be removed from the surface of the roll while the roll is unwinding.

In testimony whereof, I have hereunto set my hand. A
